In reality, most power supplies and most 8-pin plugs can support 324 watts (27 amps at 12 volt) or even 468 watts (39 amps at 12 volts) according to power supply maker Corsair. Technically, 8-pin GPU connectors support a maximum of 150 watts, for a maximum of 450 watts on paper when you use three of them. While the included adapters that come with the GPU are fine, what you plug them into is of concern. According to Intel, neither ATX 3.0 nor the PCI SIG group has sanctioned the use of adapters-but neither forbid them either. They definitely work, but the question is whether they're legit. Nvidia's new GeForce RTX 3090 Ti was the first GPU to feature the PCIe 5.0 connector, but since there aren't any power supplies with PCIe 5.0 connectors widely available yet, board vendors included adapter cables or dongles that connect three 8-pin PCIe GPU connectors to a single PCIe 5.0 12VHPWR connector. The fix, obviously, would be to buy a larger power supply or return that graphics card for one that will fit that power supply's budget. Some GPU vendors may also opt to simply halt booting and display an error message that not enough power is being supplied as we see today.

Intel believes that in a mismatch like this, the system would hopefully boot into the OS and the graphics card vendor's driver would alert you that the GPU is now running in a power-limited mode. With PCIe 5.0 and ATX 3.0, the single connector and cables means a consumer could plug a 450-watt GPU that would have taken a triple 8-pin connector in the past, into a 650-watt ATX 3.0 power supply. That's simply not enough to power up the GPU and the system will alert you to that by not posting. Today if you take a GPU that requires three 8-pin PCIe GPU plugs and try to pair it with a current 650-watt power supply, it's unlikely to work and you'll immediately know it because that PSU may only have one or two 8-pin PCIe GPU plugs. One slightly confusing aspect of how PCIe 5.0 GPU power connectors will work is due to the same simplicity of that single plug design. The latest design from the ATX12VO 2.0 spec features a larger shroud to protect the additional 4-pins from being damaged. This is the latest PCIe 5.0 12VHPWR connector that will be used for newer graphics cards. On a modular power supply, the new cable will mate to specific PCIe outputs similar to what you see on today's PSUs. The new cable essentially replaces the need for multiple cables for higher-wattage cards. Since a 500 watt power supply is unlikely to feature a PCIe 5.0 connector that can supply 450 watts to the graphics card, the cable itself is recommended to be labeled to indicate its maximum supplied voltage. With the new PCIe 5.0 connector, the power supply and cable will be capable of supplying from 150 watts to 600 watts depending on the unit. It includes features a smaller connector attached to it carry additional signaling that lets the graphics card know how much power is available from the power supply.Ĭurrently, how much power is supplied to the graphics card depends on how many 6- or 8-pin connectors you plugged into it, with 6-pins rated for 75 watts and 8-pins rated for 150 watts. The connector obviously features 12 pins instead of the usual 6 or 8, with a very similar (but smaller) per-pin design. The eye-catching new feature of the ATX 3.0 is a inclusion of a new PCIe 5.0 12VHPWR connector. And yes-you may very well want to buy a new power supply sooner than later.

He explained not just what what ATX 3.0 is, but also the why behind the decisions behind the first major revision to PC power supplies in almost 20 years. PCWorld recently interviewed Intel's Stephen Eastman, who literally writes the power supply design guide for the company. Because Intel's footprint is so large in computers, though, its specs do typically become the defacto standard everyone coalesces around. Intel's ATX 3.0 Power Supply Design Guide isn't the company dictating to power supply companies what to make they're recommended guidelines put together with input from other companies with interests in the PC.

Dubbed the ATX Version 3.0 Multi-Rail Power Supply Design Guide, it brings into focus guidelines for power excursions to make sure high-power GPUs don't crash your PC, adds a new GPU power connector, and increases efficiency while idling. But this year, Intel unwrapped the first major overhaul to the spec since 2003 that should usher in more reliability, better efficiency, and run graphics cards up to 600 watts.
